(I work in a large, well-known used bookstore. We offer complimentary coffee and doughnuts to our patrons, but we do not have a cafe or serve any other food. The bookshelves are extremely obvious and numerous. A middle-aged man enters.)

Customer: “I’ll have a medium hot dog to go.”

Me:*laughing* “Sorry, sir! We’re fresh out of hot dogs!”

Customer:*rolling his eyes and heaving a big sigh* “Okay, then what else do you have?”

Me: “Um, we have coffee and doughnuts.”

Customer: “That’s it? You don’t have any sandwiches or anything? What kind of a restaurant is this?”

Me: “We’re a bookstore.”

Customer: “A bookstore!? But I’m hungry!”

Me: “Well, like I said, we do have coffee and doughnuts–”

Customer: “Forget it! I’ll find another restaurant. This is ridiculous!”
